Repeat of this popular deal from Points hack but this time direct from Citi Bank: https://www.ozbargain.com.au/node/836040
$8k spend over 3 months is high but you can still take advantage of Payall before it closes down from 20 January.
If you don't elect for auto-sweep you'll receive 220k Citi points instead and these can be manually converted to Flybuys (1:1) or Velocity (2:1) from Citi Rewards store.
Citi credit team are really quick at processing applications. I applied for the Points hack offer last month and was approved and received card within 5 business days of applying.
is using payall still free of charge
